This Switch toggles the title.

class MyWindow : Gtk.ApplicationWindow {

	internal MyWindow (MyApplication app) {

		Object (application: app, title: "Switch Example");

		this.set_default_size (300, 100);

		this.border_width = 10;

		var label = new Gtk.Label ("Title");

		var switcher = new Gtk.Switch ();

		switcher.set_active (true);

		switcher.notify["active"].connect (switcher_cb);

		var grid = new Gtk.Grid ();

		grid.set_column_spacing (10);

		grid.attach (label, 0, 0, 1, 1);

		grid.attach (switcher, 1, 0, 1, 1);

		this.add (grid);

	}

	void switcher_cb (Object switcher, ParamSpec pspec) {

		if ((switcher as Gtk.Switch).get_active())

			this.set_title ("Switch Example");

		else

			this.set_title ("");

	}

}

class MyApplication : Gtk.Application {

	protected override void activate () {

		var window = new MyWindow (this);

}

int main (string[] args) {
